Wet Meadow
A wet meadow is a type of wetland with soils that are Solubility, saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Hydrology and ecology Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of Flood, inundation and longer periods of Hydric soil, saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do ...

Rhexia
''Rhexia'' is a genus of flowering plants in the family Melastomataceae. ''Rhexia'' species are commonly called "meadow beauty" and 11 to 13 species of ''Rhexia'' have been recognized depending on different taxonomic treatments. Distribution Unlike other members of the same family showing pantropical distribution, ''Rhexia'' is mainly distributed in temperate region of southeastern part of North America; from Nova Scotia to Florida and the West Indies (Cuba, Hispaniola, and Puerto Rico) and west to eastern Texas. The species of ''Rhexia'' are frequently found in wet meadows, coastal plain marshes, sandy wetlands and lake edges, pine woods, and road-side swales. Most ''Rhexia'' species successfully establish on open areas disturbed by recurrent burning or reclamation. Description ''Rhexia'' species are herbaceous perennials. Opposite leaves are simple, ovate to lanceolate and have the typical acrodromous venation (prominent arcuate nerves) characteristic of the Melastomatace ...

Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ...

Flatwoods
Flatwoods, pineywoods, pine savannas and longleaf pine–wiregrass ecosystem are terms that refer to an ecological community in the southeastern coastal plain of North America. Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine (''Pinus palustris''), and slash pine (''Pinus elliotii'') in the tree canopy and saw palmetto ('' Serenoa repens''), gallberry (''Ilex glabra'') and other flammable evergreen shrubs in the understory, along with a high diversity of herb species.Platt, W.J. 1999.

Savannas
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the Canopy (forest), canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoe ...

Woody Plant
A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. In cold climates, woody plants further survive winter or dry season above ground, as opposed to Herbaceous plant, herbaceous plants that die back to the ground until Spring (season), spring. Characteristics Woody plants are usually trees, shrubs, or lianas. These are usually perennial plants whose stems and larger roots are reinforced with wood produced from secondary xylem. The main stem, larger branches, and roots of these plants are usually covered by a layer of Bark (botany), bark. Wood is a structural cell (biology), tissue that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. Woody plants, like Herbaceous plant, herbaceous perennials, typically have a Dormancy, dormant period of the year when growth does not take place. This occurs in Temperate climate, temperate and Continental clima ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drosera
''Drosera'', which is commonly known as the sundews, is one of the largest genus, genera of carnivorous plants, with at least 194 species. 2 volumes. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilage, mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with ''Drosera rotundifolia'' which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Taxonomy The botanical name from the Ancient Greek, Greek ''drosos'' "dew, dewdrops" refer to the glistening drops of mucilage at the tip of the gla ...

Sarracenia
''Sarracenia'' ( or ) is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers. The genus belongs to the family Sarraceniaceae, which also contain the closely allied genera '' Darlingtonia'' and '' Heliamphora''. ''Sarracenia'' is a genus of carnivorous plants indigenous to the eastern seaboard of the United States, Texas, the Great Lakes area and southeastern Canada, with most species occurring only in the south-east United States (only '' S. purpurea'' occurs in cold-temperate regions). The plant's leaves have evolved into a funnel or pitcher shape in order to trap insects. The plant attracts its insect prey with secretions from extrafloral nectaries on the lip of the pitcher leaves, as well as a combination of the leaves' color and scent. Slippery footing at the pitcher's rim causes insects to fall inside, where they die and are digested by the plant with proteases and other enzymes. Description ''Sarracenia'' are herb ...

Calopogon
''Calopogon'', grass pink, is a genus of terrestrial orchids (family (biology), family Orchidaceae). The generic name is from Greek language, Greek and means "beautiful beard", referring to the cluster of hairs adorning the Labellum (botany), labellum. The five species are native to the eastern United States, eastern Canada, Cuba and the Bahamas. The genus ''Calopogon'' is abbreviated Cpg in trade journals. ''Calopogon'', like many other orchids, is an indicator species for good remnant hydrology. This means that their presence is an indication of high-quality ground and surface water. Most species of ''Calopogon'' frequent wet, sunny swales, bogs, and the edges of marshy areas, and associate with ferns, sedges, grasses and forbs. ''Calopogon oklahomensis'' has been observed in drier areas than ''Calopogon tuberosus'' would prefer. One distinguishing feature of the grass pinks is that, unlike most orchids, they are resupination#Orchidaceae, non-resupinate. The lip of calopogon ...
